I also don't want to seem condescending, but I urge you to get the basics of setting up your gear off pat, before attempting anything more than
single photos. Stacking is very definitely a case of running before you can walk. You won't produce decent pics by bypassing the essential first steps. Before moving on to stacking, you need to know that your mount is accurately polar aligned, your scope is reasonably well collimated, and
any cone error adjusted out. Astrophotography is a fairly steep learning
curve; there are no short cuts. Good luck.
